The developers are working on improving the model of the 3-X Particle Disruptor and how to make it fit into natural gameplay such as spawning. Because of this, 3-X Particle Disruptor can only be acquired via Remote Admin and SCP-914.

The 3-X Particle Disruptor is a Fusion Weapon in SCP: Secret Laboratory. It is a powerful and rare weapon, effective towards both human and SCP targets.

In Game

The 3-X Particle Disruptor is a powerful weapon, capable of shooting only five times before malfunctioning, becoming unusable. The weapon does not shoot immediately, instead, it has a short wind-up animation as it charges up. The firearm will then emit a warning beep before shooting. Afterwards, the player will automatically reload, which takes nine seconds.
Aiming through the sights shows a glitched screen displaying a zoomed in view. It has no available attachments.

Instead of bullets, the 3-X Particle Disruptor uses what is referred to as SCP Fusion Ammo (SFA). This is a clear liquid that, when mix with the blue catalyst, creates a chain reaction inside the firearm. After a short delay (2.2667s), the weapon fires a beam that deals 200 damage on direct hit. The beam entirely bypasses Armor, Artificial HP, and Hume Shield (other effects, like SCP-106's damage resistance, still apply). The weapon has an area of effect blast that allows it to still damage targets if a direct hit is missed.
The beam is capable of destroying doors as well as setting off Grenades and SCP-018 at long range. The weapon also penetrates through glass a couple times, before shattering it.
Terminated targets disintegrate floating upwards instead of falling. The 3-X Particle Disruptor is hitscan in practice, the trail like effect it creates does not need to line up with its targets.

The weapon's power makes it effective to kill a small group of people, but the long reloading time leaves the player open. Due to the fact that the 3-X PD bypasses a SCP's Hume Shield, it can be used in dealing permanent damage to a SCP, or possibly kill one on low health. The 3-X Particle Disruptor is also capable of destroying instances of SCP-244 and Tantrum puddles left behind by SCP-173.

The chain reaction created by the SFA and blue catalyst will eventually become too much for the firearm to handle. After five uses, the weapon will malfunction and the player will drop the weapon on the ground, where it then despawns immediately. SFA is not an obtainable item ingame, unlike other ammo types.
The SFA is located inside the weapon's magazine, while the catalyst is located inside the blue battery on the right side of the firearm.

Currently, the 3-X Particle Disruptor can only be acquired via Remote Admin or by putting the Micro H.I.D. on Coarse, though the latter is a small chance.

As stated on an AMA, the weapon will eventually be obtainable elsewhere. The art team plans on remodeling the weapon to look less finished and more prototype looking, akin to the Micro H.I.D. The AMA comment can be seen by clicking here.




  • The former name of the 3-X Particle Disruptor was the 3-X Molecular Disruptor.
  • The reticle on the sight screen, a circle with 3 radial lines, is similar to the SCP logo.
  • Its design was inspired by the energy-based firearms used in very old versions of SCP: Secret Laboratory.
  • Despite leaving no bodies behind, the death message for the 3-X Particle Disruptor is "molecularly disrupted".
  • The inspect noises for the 3-X Particle Disruptor is from The Final Flash of Existence, the main theme of the game.
  • The 3-X Particle Disruptor was added in the Xmas 2021 Event and could solely be found from SCP-2536.
    • The concept of finding a new weapon in SCP-2536 is from its original file, where Class-D personnel found SCP-2536 during a breach and were gifted "anomalous weaponry."
  • The 3-X Particle Disruptor's cartridge type, SCP Fusion Ammo, was originally a pickupable ammo type in older versions of the game used by the SBX7 Pistol and Epsilon-11 Standard Rifle.
  • The Foundation Gunworks logo appearing on the model is an oversight, as the weapon was created by SCP-2536 and not the Foundation.
